Forcipulatida
The Forcipulatida are an order (biology), order of sea stars, containing three families and 49 genera. Description Forcipulatids share with the Brisingida, brisingid sea stars distinctive pedicellariae, consisting of a short stalk with three skeletal Ossicle (echinoderm), ossicles. Unlike that group, however, the forcipulatids tend to have more robust bodies. The order includes some well-known species, such as the common starfish, ''Asterias rubens''. This order can be commonly found from North Carolina in the United States all the way to Santos in Brazil. Phylogeny The order is divided into three families: * Family Asteriidae — 39 genera * Family Heliasteridae — two genera * Family Zoroasteridae — eight genera World Register of Marine Species gives another taxonomy, with 7 families and 64 genera: * Family Asteriidae Gray, 1840 * Family Heliasteridae Viguier, 1878 * Family Pedicellasteridae Perrier, 1884 * Family Pycnopodiidae Fisher, 1928 * Family Stichasteridae Perrie ...

Asterias
''Asterias'' is a genus of the Asteriidae family of sea stars. It includes several of the best-known species of sea stars, including the (Atlantic) common starfish, ''Asterias rubens'', and the northern Pacific seastar, '' Asterias amurensis''. The genus contains a total of eight species in all. All species have five arms and are native to shallow oceanic areas (the littoral zone) of cold to temperate parts of the Holarctic. These starfish have planktonic larvae. ''Asterias amurensis'' is an invasive species in Australia and can in some years become a pest in the Japanese mariculture industry. History The genus ''Asterias'' was first described by Carl Linnaeus in the 10th edition of Systema Naturae in 1758 when he published ''A. rubens''. It was for a time the only species, but by the early 1800s a few dozen taxa had been described in this genus. In 1825 Thomas Say listed six species native to the coasts of the United States (which at the time consisted of the east coast from M ...

Asterias Rubens
The common starfish, common sea star or sugar starfish (''Asterias rubens'') is the most common and familiar starfish in the north-east Atlantic. Belonging to the family Asteriidae, it has five arms and usually grows to between 10–30 cm across, although larger specimens (up to 52 cm across) are known. The common starfish is usually orange or brownish in color, and sometimes violet; specimens found in deeper waters are pale. The common starfish is found on rocky and gravelly substrates where it feeds on mollusks and other benthic invertebrates. Description The common starfish normally has five arms, broad at their base and gradually tapering to a point at their tips, which are often turned up slightly. There is a line of short white spines running along the centre of the aboral (upper) surface of the arms with low, soft mounds called papulae on either side. The oral (lower) surfaces of the arms have rows of small tube feet, used in locomotion and feeding. The starf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leptasterias Hexactis
''Leptasterias hexactis'' is a species of starfish in the Family (biology), family Asteriidae, commonly known as the six-rayed star. It is found in the intertidal zone of the western seaboard of the United States. It is a Predation, predator and is unusual among starfish in that it Egg incubation, broods its eggs and young. Taxonomy ''Leptasterias hexactis'' forms part of a species complex. Over the years, various authorities have discussed the phylogenetic relationships of ''L. epichlora'', ''L. aequalis'' and ''L. hexactis'', all species of ''Leptasterias'' found in the north west Pacific Ocean. The authorities were Bush (1918), Fisher (1930), Chia (1966), Kwast (1990) and Stickle (1992). More recent morphological and behavioural studies have resulted, according to the World Register of Marine Species (WoRMS) in the retention of a single species, ''L. hexactis'', with the other two being considered synonyms. WoRMS now recognizes three subspecies, ''L. hexactis hexactis'' (Stimp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
